Crystal Plane Impact of ZnFe2O4–Ag Nanoparticles Influencing Photocatalytical and Antibacterial Properties: Experimental and Theoretical Studies

“…While it was 92.2% for ZnFe 2 O 4 –Ag (2.5%), 52.4% for ZnFe 2 O 4 , and 40.8% for Fe 3 O 4 under visible light observing a greater oxidation rate for ZnFe 2 O 4 –Ag (2.5%) ( k = 5.5 × 10 –3 min –1 ) as opposed to others ( k = 2.0 × 10 –3 min –1 for ZnFe 2 O 4 and k = 1.1 × 10 –3 min –1 for Fe 3 O 4 ). The present results are consistent with the reported work, that is, for bare ZnFe 2 O 4 and Bi 2 WO 6 , the RhB photodegradation was just 28% and 44% under visible light, respectively; however, the percentage was increased to 76% when it was modified to Bi 2 WO 6 /ZnFe 2 O 4 . For ZnFe 2 O 4 , it was reported around 60%, and the value was relatively higher in the other studies. , This indicates that without any catalyst, the oxidation of RhB was found to be less than 5.0% even after 3 h of irradiation, and it was increased to 31% after 3 h of irradiation in the presence of ZnFe 2 O 4 (Zn x Fe 2 O 4 ).…”

l-Methionine-Zr complex supported on magnetic ZnFe2O4 as a novel, green, and efficient heterogeneous magnetic nanocatalyst for the synthesis of 1H-tetrazole and polyhydroquinoline derivatives

“…[13][14][15] Recently, the use of magnetic nanoparticles as a catalytic support in the preparation of nanocatalysts via green methods has been considered by scientific researchers. 9,16,17 Magnetic materials such as zinc ferrite, due to their unique and non-toxic magnetic properties, 18 good biological compatibility, 19 and adjustable magnetic properties, 20 have been used in various fields including cancer therapy, 21 drug delivery, 22 and targeting. 23 Magnetic nanoparticles have properties such as a high active surface area, recyclability, chemical and thermal stability, and have been introduced to separate different types of heterogeneous catalysts.…”

Progress in the Preparation and Modification of Zinc Ferrites Used for the Photocatalytic Degradation of Organic Pollutants

“…In the past, the crystal structure of ZnFe 2 O 4 at the nanoscale was thought to be a complex spinel structure (i.e., (Zn 2+ 1−λ Fe 3+ λ ) (Zn 2+ λ Fe 3+ 2−λ ) O 2− 4 [ 37 , 38 ]). In recent years, a crystal structure that is composed of a single-phase mixture of normal spinel and inverse spinel crystals has also been proposed [ 39 , 40 ].…”
